I've played tennis against 6 ft women and against 6 ft men. I can rally with with women all day but not so with the men. They hit the ball so much harder with much more spin, much like a pitcher that throws a "heavy" pitch in baseball.
Now think of the difference in striking speed and force in combat sports...
I remember a few years back many were saying Serena Williams could compete with the men all the while ignoring reality...

1998: Karsten Braasch vs. the Williams sistersedit
Another event dubbed a "Battle of the Sexes" took place during the
1998 Australian Open[63] between
Karsten Braasch and the
Williams sisters.
Venus and
Serena Williams had claimed that they could beat any male player ranked outside the world's top 200, so Braasch, then ranked 203rd, challenged them both. Braasch was described by one journalist as "a man whose training regime centered around a pack of cigarettes and more than a couple of bottles of ice cold
lager".
[64][63] The matches took place on court number 12 in
Melbourne Park,
[65] after Braasch had finished a round of golf and two
shandies. He first took on Serena and after leading 5–0, beat her 6–1. Venus then walked on court and again Braasch was victorious, this time winning 6–2.
[63] Braasch said afterwards, "500 and above, no chance." He added that he had played like someone ranked 600th in order to keep the game "fun"
[66] and that the big difference was that men can chase down shots much more easily and put spin on the ball that female players could not handle. The Williams sisters adjusted their claim to beating men outside the top 350.
